Search the Internet and you’ll find several videos and forum threads about diagnosing and fixing a noisy compensator on a Harley-Davidson* motorcycle.

The compensator acts as a shock absorber to prevent engine vibration from affecting the transmission. It can wear over time, leading to a knocking or ticking noise. Replacing a worn compensator easily costs a couple hundred dollars, depending on the bike.

Choose the right oil

The best thing riders can do to avoid this fate is use a premium motorcycle oil that fights compensator wear in the toughest conditions.

Some oils can lose viscosity (become thinner) due to extreme heat. Powerful air-cooled V-twins are especially prone to the effects of increased heat, especially when riding in slow-moving rally traffic on a hot summer day.

Adding to the challenge, the churning action of transmission gears can shear the oil molecules and further reduce oil viscosity. Oil that has lost viscosity doesn’t form the thick, durable oil film needed to protect components against wear.

As a result, compensator and transmission gear wear can set in, leading to loud “thunks” and inconsistent shifts.

AMSOIL delivers proven protection

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is an excellent all-around lubricant that fights extreme heat and mechanical shear. In fact, it resists viscosity breakdown 6X better than Harley-Davidson SYN3* for improved protection against compensator and transmission gear wear. It helps reduce compensator noise while promoting smooth, consistent shifts.
